That's assuming the dates on the EU/DE/FR pages are accurate though. Neither the NA or JP pages mention the voting period at all. There's actually quite a bit different between the JP/NA and the EU/DE/FR versions of the page, like they used two different templates and just changed the language accordingly. The EU has some pretty strange laws when it comes to contests and online content so the differences might be attributed to that.
The fact that the JP page doesn't give any mention of the voting period is a big red flag to me that the EU pages might simply be wrong.
